Production-Injection Packers

The Heavy Duty Single Set Production-Injection Packer is used for isolating zones in open-hole or in casing. The tool is retrievable and may be used for testing, treating, production, or injection. The Heavy Duty Single Set, Rotational Release and Pull Release Production-Injection Packer may be used in vertical or deviated wells.

Inflatable packer elements for these tools are 66 inches (1.67 m) in length with 4 foot (1.22 m) seal lengths. High strength aircraft cable is used to provide good expansion characteristics in washed out or irregular well bores, as well as to provide high differential pressure capabilities. Cable reinforcement allows these inflatable packer elements to return very close to the original run-in diameter. In addition, these elements are less likely to lose rubber down hole because superior bonding occurs between the rubber and cable.

Features Heavy duty 3-1/2” & 4-1/2” IF connections Constructed with high alloy steels for unsurpassed strength Inflatable Packer Elements provide greater clearance through restrictions in

a well Tool requires no rotation for setting the packer (or releasing for shear style

tool) The system does not depend on a poppet valve to maintain pressure in the

packer element. A sliding sleeve is mechanically shifted to maintain inflation pressure in the packer.

A cable-reinforced packer element provides superior bonding of rubber to cable, and therefore less rubber is likely to be lost downhole

The system allows pressure to be fully equalized across the packer element prior to unsetting the packer. This minimizes packer element damage

Production-Injection Packers

Operating Sequence Prior to running the Heavy Duty Single Set Packer into the well, a decision must be made whether to run a solid pumpout sub, ball shear assembly, or a bull plug, at the bottom of the tool, along with a rotational or pull release mechanism. A solid pumpout sub will not allow tubing to fill as the tool is run into the well. A ball shear assembly allows the tubing to fill as the tool is run into the well. As well, fluids may be circulated down the tubing before dropping the ball from surface. Shear Pins are used in both the solid pumpout sub and ball shear assemblies and these may be set at a pre-determined value based on accessory tools used, and downhole operating conditions. A pumpout sub is normally used in highly deviated or horizontal wells. A Bull Plug is typically used for bridge plug applications.

For unsetting a Rotational Release Single Set Packer, a slight upward pull is applied to the tool followed with right hand rotation to the tubing string. Six rotations are required at the tool for release from the housing and opening bypass ports for packer element deflation.

For unsetting a Pull Release Single Set Packer, an overpull to the tool is required to shear the screws. Once sheared from the housing bypass ports are exposed and the packer element deflates.
